rectangular tube aluminum maximum bending

For this project, Chicago Metal Rolled Products (CMRP) provided 14” x 4” x 3/8” bent rectangular tubing that was rolled to inside radii from 17’ to 21’, with a 10.9° pitch.

Rectangle Tube Bending. STP’s rectangular tube bending and welded assembly fabrication services are ideal for customers who don’t have the capacity or equipment needed for project completion, are facing tight deadlines, seeking to reduce expenses or pursuing tasks outside of their specialization. Automotive, furniture, appliance, sporting goods, construction and temporary building applications commonly use rectangular tubing.

Rectangular Tube the Hard Way: 20" x 12" x .625" (Maximum mill produced size-bending capacity is greater) Rectangular Tube the Easy Way: 20" x 12" x .625" (Maximum mill produced size-bending capacity is greater) Square Tube: 16" x 16" x .625" (Maximum mill produced size-bending capacity is greater) Square Tube Diagonally

How to bend rectangular aluminum tubes You can bend certain extruded aluminum tubes, U channels and square and T shapes. However, there is a limit to the curvature before the etreme fibre will fail. Normally you need a piramid type three roller "roll forming" machine.

The Cadillac of hydraulic tube benders is the Baileigh RDB-125 Hydraulic Rotary Draw bender. You can bend up to about 2.5″ OD Aluminum Tubing on it (!) And with the degree ring guage and it’s perfect for any sort of repeat parts style bending you want to do.

Minimum roll bending radius is 7 x D It is technically feasible to be tighter than 7 x D but it depends a lot on wall thickness and material properties, so for safety stick to this guideline. There is no maximum limit to the radius from roll bending, except of course leaving the tube straight, which is the same as an infinite bend radius!

After 50 years of experience, we now offer our customers access to the latest in CNC tube bending technology for round, square, rectangular, and profile shaped tubes made from carbon steel, aluminum, and stainless steel. We do rotary bending as well as push roll bending using a mandrel on tube sizes from 1” to 10” and lengths up to 20’.

Benefits of Tube Bending. When we discuss tube we are, of course, referring to rigid metal tube (or pipe) normally manufactured from mild steel, stainless steel, aluminium or copper, and normally circular in cross section, although square or rectangular (box) section is possible and even oval shapes or more complex sections can be bent.

Bending: Design for Strength, Stiffness and Stress Concentrations7/6/99 4 next size tube with commensurate wall size is 1 1/2 in OD which greatly exceeds spec #3. However, 3/4 in pipe has dimensions: 1.05" OD × 0.113" wall.

For square/rectangular tubular elements as well, the feasibility analysis of the tube bend is made considering the mean axis and thus the mean bend radius. When ordering, however, it is important to refer to the inner bend radius. This because the bend matrix for a square/rectangular tube is different from that for round tubes.

3. 6061. This is one of the most versatile of the heat treatable family of alloys. In the annealed condition, it can be used for bending since the difference between yield and tensile strength is 10 Ksi and elongation is up to 18%. When moving up to T4 and T6 tempers, however, bending ability tends to decrease.

This is one of the strongest aluminum alloys, and is not very weldable and is very difficult to bend. ASTM A53 Pipe: See our discussion on the bender tech page-“Tube vs Pipe”. This medium/low strength steel is manufactured to the requirements set by the American Society for Testing and Materials (ASTM), document A53.
